  ++ Description

  Integrate the Z-Push library into Horde. Provide the ability for  
Horde to provide over the air synchronization of email, contacts, and  
calendar data to devices such as the iPhone/iPod Touch, Android and  
any other system supporting !ActiveSync.

-Rough outline of integration plan:
-
-# Using out of the box Z-Push install and the "diff" backend,  
implement a basic driver for sync'ing email, contacts and calendar  
info. Currently, IMAP "push" email is working. Don't spend a lot of  
time making this driver perfect, it's basically a proof of concept /  
prototype.
-# Identify code within Z-Push that can be replaced with Horde  
libraries. For example, mime handling, IMAP server communication,  
WBXML document creation/parsing.  Much of the supporting z-push code  
could be replaced by using the appropriate H4 library.
-# Z-Push needs to be PHP5-ified.
-# Refactor Z-Push into a Horde_ActiveSync library, and provide an  
endpoint for accessing it. Endpoint probably integrated into existing  
rpc.php for now. This phase will include rewriting the horde driver  
and replacing/augmenting the functionality of Z-Push's "diff" backend  
with Horde History. Look at !SyncML code for how to use the history  
backend to retrieve the needed data.
+++ Rough list of issues/todos in no particular order

+Need to implement ghosted properties / SUPPORTED tag. Currently, all  
data on the server is overwritten and replaced with only what the PIM  
sends. It's possible for some PIMS to ghost contact and calendar  
properties so that only the supplied tags are changed, and missing,  
ghosted properties are retained on the server.  When a PIM supports  
this, it sends a SUPPORTED tag with children representing the  
NON-ghosted properties. Based on other clients I see, it appears that  
the absence of the SUPPORTED tag would indicate that any property not  
transmitted should be handled as a ghosted property??
